I just picked up a used ZEX nitrous kit for my H22 hatch. I cant find any good detailed installation details and didnt know if anyone had some good tips for me. I am going to spray a 55 shot dry. I have a chipped P28 ecu with the stock rev limiter.......do I need any parts that dont come with the kit to be safe? It came with a bottle heater and purge kit. Also a pressure guage. All the internals are stock on my H22, the bolt on details are in my signature. Let me know what you guys think.
